Application tiled March 14,1913. Serial No; 754,340.

T0 all whom it may concern Be it known that I, GEORGE SAMUEL BAKER, of the firm of Joseph Baker & Sons Ltd., a subject of the King of England, residing at Willesden Junction, N. W., London, in England, have invented certain new `and useful Improvements in and Relating to assume for a short distance a more or less sharp rise or upward inclination, which is then followed by a gentle downward declivity of the said base to a point near the discharge end from which latter point to the actual discharge the base may be given a still sharper downwardinclination, the lowermost point at said discharge end being preferably in a lower plane than the lowest part of the base at the inlet. rlhe upperyrun of the traveling sole plate which in effect constitutes the base of the chamber obviously follows the .Course above de.

scribed. By this means the heat in the baking chamber and steam given olf by goods being baked rises to the uppermost part of the sole or base which is close to the inlet end of the chamber so that goods to be baked are quickly introduced to the most heated air and to the greatest volumev of.

steam, which prevents the'formationof an outer hardened crust on the goods and insures a more complete baking throughout, thusimproving the quality and appearance of the baked goods.

The invention is hereinafter fully described and the novel features specifically pointed out in the appended claims, reference being made to the accompanying draw- A ing which is a longitudinal section of an oven to which the present' invention has been applied. with automatic feed and discharge devices represented diagrammatically. .z s

In the drawing, a designates the framing or masonry of the oven'which together with the flues mayybe of any desired or convenf tional form and form no part of the 'present invention, and b is the baking chamber having the inlet openingb1 and the discharge opening b2.. Within said baking chamber is the traveling sole plate o, the upper run or stretch of which constitutes the effective base of the chamber, said sole plate passing at each end about polygonal -rollers c1, 01 and being conducted in the course desired vby guides c2. The said upper run of the sole plate is so guided that commencing at or about the inlet aperture b1 it rises somewhat sharply for a short distance as at d to a point d1 which is the highest part of the base and is then followed by a portion d2 which declines gently downward to a point d3 near the discharge opening b2 from whichlatter point vthe sole plate inclines `more sharply vas at d4 to its outlet end, the latter thus being at a lower plane than the corresponding part at the inlet end.

lt will be observed that the ends of the traveling sole plate-that is, the greater inclined end portions, extend so as to-directly underlie the feeding and discharge parts or mechanisms at the opposite ends of the ovens, so that the material being fed into the oven may be placed directly upon the inclined prortion of the plate at the feed end of the machine, and taken directly fromv the inclined portion at the discharge end of the machine, thereby facilitating the loading and unloading of the oven; and enabling the projecting of the opposite ends of the sole plate outwardly from the actual baking chamber where the 'loading and unloading may be accomplished at points relatively cool compared to the heat of the baking chamber itself. 4

The purpose of this construction is stated above, and it will be obvious that the heated air and steam will rise and flow along the chamber, and accumulate to the greatest eX- Atent at orabout the point d1, where the goods soon after entering the chamberare subjected to the influencethereof. v

. In this igure an automatic feeding device is designated as a whole by the character e to secure by Letters Patent of the United 1. In a bakers oven, a b aking chamber having an inlet at one-end and an outlet at the other end and an endless sole plate adapted to travel through said chamber and directly receive the goods to be baked, said sole' plate at the inlet end of said chamber being inclined upwardly for a short distance, then inclined downwardly in a rectilinear path with a gentle declivity to near the discharge end, and then again more sharply downwardly in the' same direction to its termination substantially as and for,

' the purpose described.

2. In a bakers oven, a baking chamber having an inlet at one end and an outlet at the other end and an endless sole plate adapted to travel in a circuitous-fpath through said chamber and directly receive the goods to be baked,'said sole plate at the inlet end of said chamber being inclined 'upwardly for a short distance, then inclined downwardly in a rectilinear path with a gentle declivity to a point adjacent the dis-l chargeend of said chamber, and thence again more sharply downwardly in the same f direction to said discharge end, the lowermost part of the discharge end of `thesole plate bein in'a lower plane than the corresponding owermost part of the sole plate at the inlet end substantially as and for the purpose described.

3.- In a bakers oven, a baking chamber having feeding and discharge devicesassociated therewith, and movable supporting means within thevbaking chamber for initially elevating the material being baked to a relatively'high point'in the oven, and for lowering said material as it approaches the outlet of the oven, said movable supporting means projecting outwardly below a part of" the feeding means substantially as described.

4. In a bakers oven, a baking chamber having feeding and discharge devices associated therewith, and movable supporting means within the baking chamber for initially elevating the material being baked to a relatively high point lowering said material as it approaches the outlet of the oven, said movable supporting means projecting outwardly in opposite directions below portions of said feeding and discharginl means. v

5. In v'a akers oven, a baking chamber having feedin 'and discharge devices asso'- ciated therewlth, and movable supporting means within' the baking chamber for initially elevating the material being baked to a relatively high point in the-oven, and for lowering said material as it approaches the outlet of the oven, said movable supporting means projecting at its feed end outwardly beyond the baking chamber. K

6. In a bakers oven, a baking chamber having feeding and discharge devices asso in the oven, and for ciated therewith, and movable supporting means within the baking chamber for initiall elevating the material being baked to a re atively highpoint in the oven, and lfor lowering said material as it vapproaches the outlet of the oven, said movable supporting means projectlng at opposite ends outwardly beyond the baklng chamber.

In witness whereof; I have signed this specification in the presence of two witnesses.
